Passive tension is the force exerted on a muscle when it is stretched, while active tension is the force generated by the muscle when it contracts.
Thermal tension occurs when there is a difference in temperature between two adjacent materials or components, causing them to expand or contract at different rates. This difference in expansion and contraction can lead to stress and potential damage within the materials. Managing thermal tension is important in engineering to prevent issues like warping or cracking.
Isometric contraction. This type of contraction occurs when the muscle generates tension without changing its length, such as when holding a weight in a fixed position.
Liquids with high surface tension have stronger forces between their molecules at the surface, causing them to form droplets and resist spreading. Liquids with low surface tension have weaker forces, allowing them to spread out more easily and wet surfaces.
In physics, tension refers to the pulling force applied to an object, often through a rope or cable. Pressure, on the other hand, is the force applied perpendicular to the surface of an object, typically measured as force per unit area. In summary, tension acts along the length of an object, while pressure acts perpendicular to the surface of an object.
Compression occurs when an object is squeezed or pressed together, causing it to shorten or compact. Tension, on the other hand, happens when an object is stretched or pulled apart, causing it to elongate or expand. Both compression and tension are types of forces that can act on materials.
Thermal tension occurs when there is a difference in temperature between two adjacent materials or components, causing them to expand or contract at different rates. This difference in expansion and contraction can lead to stress and potential damage within the materials. Managing thermal tension is important in engineering to prevent issues like warping or cracking.
An isometric contraction builds tension but there is no joint movement.

Unfused tetanus-"the relaxation time between successive twitches will get shorter as the strength of contraction increases in amplitude." On the other hand, Fused tetanus-"Smooth, sustained muscle contraction."
It is called concentric isotonic contraction.
Isotonic contraction
When muscles are stimulated, they contract, causing the muscle to become shorter. The force applied is therefore a tension. Most muscles are arranged in pairs so that each can apply tension to move a joint in either direction. Obvious examples of the pairing of muscles can be seen at the elbow and knee.
Isometric
compression zone is an positive zone,tension zone is an negative zone..
tracheal deviation
An isometric contraction is the name given to a skeletal muscle that does not shorten, but increases tension. The muscles generate force to protect themselves.
